Ichazwa yi-ANSI njengeyunithi yenqanaba le-frequency xa isiseko se-logarithm sisibini.
Ubudlelwane be-octave yinto yendalo eye yabizwa ngokuba "ummangaliso osisiseko womculo", ukusetyenziswa kwayo "kuqhelekileyo kwiinkqubo ezininzi zomculo".
Ezona zikali zomculo zibalulekileyo zidla ngokubhalwa kusetyenziswa amanqaku asibhozo, kwaye isithuba phakathi kwamanqaku okuqala nesokugqibela yi-octave.
Ngokomzekelo, i-C Major Isixa iqhele ukubhalwa ngeCDEFGABC, iC yokuqala neyokugqibela ibe yi-octave ngokwahlukeneyo. Amanqaku amabini ahlulwe nge-octave anegama lonobumba ofanayo kwaye akwiklasi yepitch efanayo.
Imizekelo emithathu eqhele ukucatshulwa yeengoma ezibonisa i-octave egqibeleleyo njengethuba labo lokuvula “Singin’ emvuleni”, “Ndaweni ithile ngaphaya koMnyama”, kunye “neStranger on the Shore”.
Ikhefu phakathi kwe-harmonics yokuqala neyesibini yochungechunge lwe-harmonic yi-octave. I-octave ngamanye amaxesha ibizwa ngokuba yi-diapason.
Ukugxininisa ukuba lelinye lamathuba agqibeleleyo (kubandakanywa unison, isine esigqibeleleyo, kunye nesihlanu esigqibeleleyo), i-octave ityunjwe i-P8.
I-octave ngasentla okanye ngaphantsi kwenqaku elibonisiweyo ngamanye amaxesha lifinyezwa 8va (= Italian all'ottava), 8va bassa (= Italian all'ottava bassa, ngamanye amaxesha kwano 8vb), okanye ngokulula 8 kwi-octave kwicala elibonisiweyo ngokubeka olu phawu ngasentla. okanye ngaphantsi kwabasebenzi.
NdinguJoost Nusselder, umseki weNeaera kunye nomthengisi womxholo, utata, kwaye ndiyakuthanda ukuzama izixhobo ezitsha ngesiginkci entliziyweni yothando lwam, kunye neqela lam, ndisenza amanqaku eblogi anzulu ukusukela ngo-2020. ukunceda abafundi abathembekileyo ngokurekhoda kunye neengcebiso zesiginci.
